Farra levure' To all, w21/0m it may cori/cern:

Be it known that l, Farra Gurmrmab rikant, a subject ofthe King of 'russia, residing at Berlin, Alte Jalrobstr 173, Germany, have invented certain neviT and useful im provelrnents in Electricallydieated Stoves, of which the following is a specification, reference being had therein to the accompanying drawings. The invention relates to a stove that is vided with an electric heating device, that combine's'the advantages of an electr heater with the comfort of a tiled stove. The -main heating devices of` steam electric heating systems as at present oonstructed 'are subject :to the disadvantage that they are, comparatively, ol small e, and that they consequently possess l, lL superlicial area, with the result that the air must be partially superheated in order heat an apartment to the same extent as an apparatus possessing a larger surface; 'while a further disadvantage results from the that, their volume being small, they are unable to store up and giveont a large quam tity offbeat. The rapidity with which, in apparatus of this class, cooling taires place, and the resulting inequalities in the amounts of heat given out, are the direct outcome, on the one hand, of their low heat-storing capacity, and, Lon the other hand, of the e2;- cessive heating due to their small surfaces.

Now this invention has for object to obe viate the defects above: referred to, and to this end, in stoves in accordance therewith,

the heating' device is arranged to heat a large stove capable of storing a considerable quantity of heat, and of radiating in a fairly uniform manner while the surface of .the heating device itself is, moreover, rela In consequence of this rangement the heat is both uniformly radiated and uniformly diffused through the apartment, while the superheating and consequent disagreeable dryness of the air which has heretofore 'usually taken place is obviated.

The accompanying drawing illustrates ap- I `paratus in 'accordance with this invention;

vthere is arranged the heating device Figure 1 being a vertical and Fig. 2 Zontal section thereof. i

When the iated, the cold. air ascends e i, y e 5, 7, along the wall 8, l surplus air due to expansion in conf le he at escapes through the pas- Y, however, this latter passage anged ui the lower part of the stove, or y sa much. hot air escapesas lsnecessltie Jnsion.

"' able for a room of ordinary d, be heated in one hour by a current-of llrilowatts to an extent suilicient to enable it to radiate heat in a practically uniform manner during a period of from 8 to 9 hours; while the room is comfortably heated in about half an hour, The currentcan he cut olf after the lapse of one hour, or, if it is desired that the stove should retain its heat for a longer period than from 8 to 9 hburs, the current can he reduced to a minimum.
